The subject says it all pretty much, is it possible to turn off the reporting of version data in response to GET [http://localhost:9200](http://localhost:9200)?

From what I can tell from the code, it appears that you can disable returning the version field. -- Ivan On Thu, Dec 19, 2013 at 12:27 PM, Josh Harrison [hijakk@gmail.com](mailto:hijakk@gmail.com) wrote: > The subject says it all pretty much, is it possible to turn off the > reporting of version data in response to GET [http://localhost:9200](http://localhost:9200)? > Thanks, > Josh > > -- > You received this message because you are subscribed to the Google Groups > "elasticsearch" group. > To unsubscribe from this group and stop receiving emails from it, send an > email to [elasticsearch+unsubscribe@googlegroups.com](mailto:elasticsearch+unsubscribe@googlegroups.com). > To view this discussion on the web visit > [https://groups.google.com/d/msgid/elasticsearch/7962249a-610f-4ee6-9496-a1cf14df8d95%40googlegroups.com](https://groups.google.com/d/msgid/elasticsearch/7962249a-610f-4ee6-9496-a1cf14df8d95%40googlegroups.com) > . > For more options, visit [https://groups.google.com/groups/opt\_out](https://groups.google.com/groups/opt_out). -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

To clarify, when I go to [http://localhost:9200](http://localhost:9200), I want to get back { "ok" : true, "status" : 200, "name" : "Stem Cell", "tagline" : "You Know, for Search" } Not { "ok" : true, "status" : 200, "name" : "Stem Cell", "version" : { "number" : "0.90.5", "build\_hash" : "c8714e8e0620b62638f660f6144831792b9dedee", "build\_timestamp" : "2013-09-17T13:09:46Z", "build\_snapshot" : false, "lucene\_version" : "4.4" }, "tagline" : "You Know, for Search" } I poked around in the code and the only code place I fine "You Know, for Search" is > There doesn't appear to be an explicit flag that would allow me to suppress that, but perhaps that's somewhere else?

Just having the REST endpoint open is a security risk. 🙂 You can always put a proxy in front of elasticsearch that intercepts certain calls such as PUT, POST, DELETE or simply / in your case. Normally in elasticsearch, a request is built with various parameters via a builder and then the resulting response will have the correct fields. You can see an example with the nodes stats: [https://github.com/elasticsearch/elasticsearch/blob/master/src/main/java/org/elasticsearch/rest/action/admin/cluster/node/stats/RestNodesStatsAction.java](https://github.com/elasticsearch/elasticsearch/blob/master/src/main/java/org/elasticsearch/rest/action/admin/cluster/node/stats/RestNodesStatsAction.java) The main action does not really have specific request/response classes. You can try raising an issue or even submitting a pull request yourself, but I do not see this issue as being very important. That is just my guess. -- Ivan On Thu, Dec 19, 2013 at 2:52 PM, Josh Harrison [hijakk@gmail.com](mailto:hijakk@gmail.com) wrote: > To clarify, when I go to [http://localhost:9200](http://localhost:9200), I want to get back > > { > "ok" : true, > "status" : 200, > "name" : "Stem Cell", > "tagline" : "You Know, for Search" > } > > Not > > { > "ok" : true, > "status" : 200, > "name" : "Stem Cell", > "version" : { > "number" : "0.90.5", > "build\_hash" : "c8714e8e0620b62638f660f6144831792b9dedee", > "build\_timestamp" : "2013-09-17T13:09:46Z", > "build\_snapshot" : false, > "lucene\_version" : "4.4" > }, > "tagline" : "You Know, for Search" > } > > I poked around in the code and the only code place I fine "You Know, for > Search" is > > [https://github.com/elasticsearch/elasticsearch/blob/c20d4bb69ed29cf11a747f0fdc40ce4237f79ce4/src/main/java/org/elasticsearch/rest/action/main/RestMainAction.java](https://github.com/elasticsearch/elasticsearch/blob/c20d4bb69ed29cf11a747f0fdc40ce4237f79ce4/src/main/java/org/elasticsearch/rest/action/main/RestMainAction.java) > There doesn't appear to be an explicit flag that would allow me to > suppress that, but perhaps that's somewhere else?

Yeah, it's been looking like a proxy is the way to go. If it was an already existing functionality allowing me to suppress the version info from /, I'd have been happy to use that, but I agree - it isn't worth anyone's time to add this.

Can you explain why showing the prompt is a problem? Maybe it helps us to understand if it is a common use case and a patch for the codebase would be appropriate. As for the proxy, it is recommended to not expose ES to HTTP frontend access, so a proxy is the best method I know. ES can be well hidden in a private network like 10.0.0.0 or 192.168.0.0 - also there are a few dangerous commands, and HTTP methods like DELETE to take care of. These are open by default for maximum convenience, for admins with curl at hand, and must be protected against malevolent access, if you set up ES in a hostile environment.

They're worried that giving the exact version info of both ES and Lucene makes it easier should a threat already internally on the network attempt to compromise the system. At least I think that's the concern.

I understand. There are many methods of compromising a system. For example, blast random loads of bytes to open ports, until the process on the server dies. Or syn floods. DoS attacks are possible, as long as a port is open, like 9200. But there is also 9300. There are firewalls or other network setups that can protect backend apps from intruders and DoS attacks. As said, just hide all ES nodes from public network access, or ramp up firewalls settings. Changing the ES environment is the primary solution. Do not fight symptoms, fight the cause.
